Abstract: This study develops an integrated perishable items inventory replenishment model for decaying items with multiple market demand under volume flexibility. Flexibility is a desirable property of production systems which quite often is presented as a panacea to numerous realistic problems. The production rate is taken as flexible. Deterioration rate depends upon quality level and time. The time related function for deterioration follows a two-parameter Weibull distribution. Holding cost is taken as linear increasing function of time. To make the study realistic quality dependent setup cost has been taken. Numerical example along with graphical illustrations is presented to discuss the optimality of the model.

Keywords: time and quality dependent decaying items; volume flexibility; multiple market demand; variable holding cost.
